1. A method of decoding a video signal, comprising:

  • deriving a corresponding pixel value of a corresponding block in a first layer, the corresponding pixel value being referred by a current pixel of a current block in a second layers,obtaining a current pixel prediction value as the corresponding pixel value when a block type of the corresponding block is intra mode, andreconstructing the current block based on the current pixel prediction value and a received residual value,wherein the first layer represents a base layer, the second layer represents an enhanced layer.
